Ceiling Recessed Units

SLZ Ceiling-Recessed Indoor Units for MXZ Heat Pump Systems.

More Information

The new SLZ-KA ceiling casette systems offer a wide air-flow pattern for better air distribution offered to your customers. Installation can be done in a hard ceiling (with a access panel for servicing) or placed into a 2×2′ drop ceiling. With a built-in drain lift mechanism for condensate removal and a 4″ ventilation air intake knockout option the SLZ is ready to handle a variety of installation needs.  SLZ units on MXZ systems include the following features:

  • Wide air-flow pattern for better air distibution
  • 4″ ventillation air intake knockout
  • Built-in condensate lift mechanism

Key benefits of M-Series systems

Perfect for Hot and Cold Spots and Beyond

  • Industry leading quality and reliability
  • Minimal or no ductwork means less energy is wasted
  • Reduced installation time over conventional systems
  • Controllers allow for perfect temperatures in virtually any space – sunrooms, bedrooms, home offices, attics, basements and garage workshops
  • Inverter-driven compressors automatically adjust cooling and heating capacity for consistent temperature
  • H2i® Hyper-heat pumps with hot-start technology provide instant warmth even in extreme climates (down to -130 F)
  • Advanced filtration dramatically improves air quality
  • Maximum energy efficiency with higher SEER and HSPF ratings

Energy Efficient and Environmentally Friendly

M-Series systems utilize green technologies, and are much more efficient, so homeowners never have to sacrifice comfort over worries about high-energy costs.

  • INVERTER technology* results in substantial energy and utility savings for homeowners
  • Zone control for improved comfort and decreased energy usage
  • Many Energy Star® rated systems
  • SEER ratings as high as 26 – dramatically better than conventio nal systems
  • Local and state utility rebates and incentive opportunities
  • Environmentally friendly R410A refrigerant with zero Ozone Depletion Potential (ODP)
  • 83% of system components are recyclable
  • Washable filters made from natural materials

Product Features

Put Comfort On Cruise Control

Sophisticated, electronic control systems detect any change in room or zone temperature and—like a car’s cruise control—automatically adjust the speed of the outdoor unit’s INVERTER-driven compressor for precise capacity and temperature control.  Electronic LEVs exactly control refrigerant flow to regulate coil temperature.

Mini-split Inverter Technology

Detect & Control Temperature Fluctuations

All M-Series systems detect room temperature fluctuations and automatically adjust performance for ultimate comfort in any room.

  • All indoor models feature a return air sensor that constantly monitors and maintains r oom temperature
  • Continuous fan operation ensures temperature consistency
  • Systems with an i-see SensorTM scan the room and adjust airflow based on ambient temperature readings. (MSZ-FE09/12NA i-see Sensor models only)
  • Auto changeover feature automatically switches between cooling and heating modes as needed to maintain a consistent temperature – just set it and forget it (MUZ and SUZ outdoor units)
  • Seven horizontal airflow directions provide 150° of lateral airflow for greater conditioned air circulation (wide vane or swing mode, available on the MSY(Z)-FE09/12/18/GE24/D30 /36NA)

Multiple Filters for Cleaner, Healthier Air

Our indoor units use a sophisticated multi-part filtration system to reduce contaminants such as allergens, viruses and bacteria from the air. This combination of filters provides a healthier, breathing environment for the home.


  • Captures dust particles and absorbs odor-causing gases
  • Hybrid-coating process makes the catechin filter washable and, if properly maintained with regular cleaning, remains effective for up to ten years


Available on MSZ-FE9/12NA

  • Features a ceramic surface absorption element and uses nanotechnology for high-power odor absorption
  • Periodic cleaning, following the recommended procedures, will maintain filter effectiveness for up to two years

air filtration


Available on MSZ-FE9/12NA

  • Reduces germs, bacteria, and viruses
  • Helps trap dust, pollens, mites, and other particles
  • Utilizes an enzyme catalyst to help break down the sulfur atom bonds in allergen proteins, transforming them into nonallergen proteins, and, effectively cleaning the air (filter should be cleaned regularly to maintain effectiveness)


Total control for total comfort: single rooms can now have ultimate comfort with the power of precise control over hot and cold spots.


SLZ-KA 2’x2′ ceiling-recessed cassette units offer a wide airflow pattern for better air distribution in a less obtrusive style. Install SLZ in a hard ceiling (with an access panel for servicing) or in 2’x2′ drop ceiling.
